What is the common and/or member pronunciation of 'Marylebone' in 'Marylebone Cricket Club'?
There are lots of Internet discussions on how to pronounce 'Marylebone'. But given the context of 'Marylebone Cricket Club' (MCC), what is the most common pronunciation among UK people and/or MCC members?
The correct pronunciation is "ma-ruh-luh-buhn". This is how it is pronounced in this British Pathe newsreel from 1968: https://www.youtube.com/watch?v=8VyVUw_EktI at 0:30 and by the automated announcer on Chiltern Trains (the railway company that serves that station). The pronunciation by the automated announcers on the London Underground ("Mar-lee-bone") is wrong.
Marralabone or Marrylabone. Hope that helps. I used to work in Marylebone High Street, so that's what we all called it at the BBC.
According to the Longman Pronunciation Dictionary, the most common British pronunciation is ['mær əl ə bən], and the most common American pronunciation is ['mer əl ə boʊn], which to my ear match the audio files in the Oxford Learner's Dictionary, see here.
Two of the less common variants are ['mær ɪ bən] and ['mɑːl ɪ bən].
As a (former) north-Londoner, born to north-London parents married at Marylebone registry office, I would agree with @Amgine. Thus, borrowing @painfulenglish's phonetics, it is ['mærə ləboʊn] or ['mærɪ ləboʊn]. This was the only London district about whose pronunciation I had recurring doubt. I suspect that no single pronunciation can be pinned down as standard.
